Stuttering on Raspberry 4

[aaruni96]

I have a snapserver instance on an amd64 home server, and multiple snapclients : amd64 workstation, android, and raspberry pi 4. Only on the rpi 4, there are loads of audio stuttering problems, with an accompanying entry about pMiniBuffer. Nothing interesting appears on the server side logs.

2025-02-15 22-15-12.119 [Info] (Stream) pMiniBuffer->full() && (abs(pMiniBuffer->mean()) > 50): -50374

The raspberry pi is using alsa and playing on a speaker connected to its onboard 3.5mm audio.

The snapclient version on the rpi is snapclient v0.31.0 (rev cf2be071).

Client logs :

snapclient.log

Playback of local media on the raspberry pi works flawlessly, both via mpv, and aplay

This happens when snapcast is running in alsa mode, and also pulse mode. Any help would be appreciated @badaix

Don't know, you should have only once (not three times) the message

[Info] (Controller) Codec: flac, sampleformat: 48000:16:2

This is only logged, when the server sends it. Without server log hard to guess, why it's received multiple times.
Maybe your network connection is unstable?

Ah that's because I changed streams, my bad. Here's what I did :

start snapclient, its set to a stream with no active playback. (first time the message). Then I change it to a stream with actual playback (second time the message, and then all the failures). After sometime (once some error messages are recorded), I change it to the silent stream again (third time the message), and then I quit snapclient.

So you can disregard that part.
